Garden fleece is one of the most practical buys a UK gardener can make. It is lightweight polypropylene that costs less than a bag of compost, yet it can add several degrees of protection when the temperature drops. It is the difference between a healthy crop and a bed of blackened mush, and it stretches your growing season at both ends of the year.
Understanding GSM: the only spec that really matters
GSM (grams per square metre) tells you how heavy the fleece is, and therefore how much frost protection it gives. Here is the breakdown:
|
Weight |
Protection |
Light transmission |
Best for |
|
17gsm |
Around 2-3°C |
Very good |
Spring/autumn, seedlings, pest exclusion |
|
30gsm |
Around 4-5°C |
Moderate |
Hard frosts, winter, overwintering veg |
|
35gsm |
Around 4-6°C |
Moderate |
Exposed sites, harsh winters, tearing resistance |
|
50-70gsm |
Around 5-6°C |
Poor |
Short-term winter wraps on dormant plants only |
Fleece traps ground warmth rather than creating heat, so the maximum realistic protection is 5-6°C. Heavier fleece also cuts light, which matters for anything actively growing.
How we chose
- UV stabilisation of the polypropylene (prevents brittleness)
- Edge durability under pegging
- Honest GSM claims relative to price
- Roll sizes that suit domestic gardeners
- Availability from UK retailers, including Amazon UK

How to use garden fleece properly
Peg it down completely: Cold air flows like water, so any gap lets the warmth drain away overnight. Use ground pegs, stones or timber around the whole perimeter.
Keep fleece off foliage when possible: Direct contact conducts cold to the leaves and causes frost burn. Hoops, canes topped with inverted pots or a frame prevent this, though hardy vegetables tolerate contact.
Allow breathing on mild days: Plants sealed in heavy fleece risk rot and mildew in damp, warm spells. Open it up when the weather improves.
Frequently asked questions
Q: How many degrees of frost will garden fleece protect against?
Realistically 2-3°C from 17gsm and 4-5°C from 30gsm, with proper pegging. Doubling the layers adds a degree or two but reduces light. Nothing you drape over a plant will save it from a severe freeze.
Q: Can I leave fleece on all winter?
Light 17gsm fleece works on hardy crops year-round. Heavy 50gsm-plus material should not stay sealed all winter, as the light loss and trapped moisture create rot and mildew risks.
Q: Is fleece better than a cloche?
Cloches give consistent protection, hold their shape in wind and last for years, but they cost more and store poorly. Fleece is cheap, compact and covers bigger areas. Most gardens benefit from both.
Q: Can I use fleece against pests?
Yes, especially 17gsm. A 17gsm fleece pegged tight over carrots is an effective carrot fly barrier and protects brassicas from cabbage whites. Crops that need pollinators must be uncovered when flowering.
Q: Does garden fleece let rain through?
Yes. Spun-bonded polypropylene is permeable to air and water, so rain and watering reach the soil underneath.
Q: How long does garden fleece last?
Budget rolls typically give one to two seasons before the edges deteriorate. UV-stabilised heavier rolls can last several seasons, and jackets stored dry often last years. UV stabilisation is the critical factor for longevity.
Our verdict
Start with 17gsm fleece, and the Yuzet 17gsm sheet is the clear budget choice. For hard winter frosts, step up to a 30gsm roll such as Gardening Naturally, or the Yuzet 35g roll for exposed sites and big plots. For individual plants, jackets win: Haxnicks for standing shrubs and tree ferns, and the zipped 70gsm jackets for valuable specimens. Timing matters too: fleece is cheaper and better stocked in summer, and the first hard frost of the autumn never arrives on a convenient day.
